Patented May io, 1932 PATENT oFricE PAUL D. PHILLIPS, OF CHICAGO, ILLINOIS, ASSIGNOR TO BENJAMIN ELECTRIC MANU- FACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS WIRING TERMINAL CONS'IRUCTION' Application led September 8, 1928. Serial No. 304,650.

- My invention relates to wiring terminal construction.

'One of the objects of my invention is to provide an improved construct-ion in. which the Wiring may be eiecteld by inserting the 'bared ends'otthe'tvires into openings in the tion in which the base has openings for stocking the slack in case there is no room to push the slack back into the conduit or housing.

A further object is to provide an improved construction in which the socket interior may be secured in the shell in various adjusted positions.

Further objects will appear fronrthe description and claims.

In the drawings, in which an embodiment of my invention is shown, v

Fig. 1 is a side elevational view of a receptacle construction7 parts beingr broken away;

Fig. 2 is a bottom view of the socket interior;

Fig. 3 is an axial section of the socket interior;

Fig. 4 is ay top plan view of the socket interior; and

Fig. 5 is a perspective View of the Wiring terminal construction.

Referring to the drawings in detail, the construction shown therein comprises threaded shell and center Contact members, 1 and 2, a pair of .wiring terminal constructions 3 and 4 for these contacts respectively and an insulating base 5 on which said contacts and wiring terminals are mounted.

The wiring terminal construction shown in perspective in Fig. 5 comprises a sheet metal stamping 6 having upper and lower bearing portions 7 and 8 and an intermediate inclined backing portion 9 extending between and connecting the bearing portions, a screw l0 swiveled in the bearing openings in said spaced bearing portions and a nut 11 threaded .on said screw having a beveled edge 12 between which and the inclined backing portion the bared end 13 of the wire is clamped. The screw is held in assembled relation with respect to the stamping by pinching theend of the screw, as shown at 14, after the screw has been passed through the bearing openings. The head 15 of the screw serves to hold the receptacle contact in assembled relation with respect to the Wir- ,ing terminal, the shank of the screw passing through an opening;r in the securing portion 16 oi the receptacle contact.

The center and shell contacts are held in nlace on the insulating base by means of an insulating button or disc 17 of suitable sheet material between which and'the insulating base the securing portions 16 of the contacts are clamped. The disc is positioned bv means of an elongated boss 18 (Fig. 2) on the insulating base. which fits in a lcorresponding` shane-d hole in the disc. The disc is securedy on the insulating base by means of a pair of eyelets 19. v P,

The insulatingy base is protided with'suitable openings Q0 extending longitudinally of the axis thereof for receiving and guiding' the bared ends 13 of the Wires into proper engalement with the Wiring terminals.

In order to provide storage space for any slack in the wires which cannot be pushed back into the conduit or housing the sides of the insulating base are provided with recesses or pockets 21 to receive a loop' 22 of the Wire, passages 23 being provided in the upper side of the insulating` hase leading from the longitudinally extendingr openings 2O to the side recesses 21 respectively.

The receptacle interior is housed in a sheet metal shell 24 which also serves to cover theP side recesses 21 and top passages 23. The upper end of the sheet metal shell is secured to a hexagonal nut E25 having a hexagonal portion E26 lying inside of the shell and engaging V a. correspondingly spaced hexagon-shaped recess 27 in the upper faceof the insulating bas-e. By means of this engagement the socket interior may be Secured and positioned in the shell in various positions of angular adjustment.

In order to hold the socket interior in the shell 24 a screw ring 28 is provided, the upper edge of which engages a shoulder 29 on the insulating base 5, the ring having a threaded engagement with the lower threaded portion f)dobf the shell. fqgfenjijhlingfhe device, a subassernblyis '.'iini'di if'fthgzcentgr contact and its tegjiinnl.. constil 'etigngi'ianother subthe eyelets 19 which have al'sqlzieen in in position'on the assembly ("f'frf.-

In Wiring;r the receptacle all that is necessary to do is to operate the swig a* screws 1'() until `the nuts 11 are at the ufe 1slilg'iitof their movement, bare the ends of the Wires for about lialt an inch. insert these bared ends into the openings 2O as far as they will go, and then operate the swivel screws te draw the clamping nuts downwardly to pinch the ends of the Wires against` the ine-lined backing portions. l

vWhile I have shown but one embodiment of my invention, it is obvious that it may .he embodied in other forms covered and defined by the appended claims.

I claim:

Y l. A. Wiring'erniinal construction comprising a swivel screw held a gainst eindwise movement, a member having a pair oit spaced bearing portions in which said screw is swiveled and an intermediate inclined backing' portion, and a nut between said hearing` portons engagged and moved axially hy said screw, bebetween which nut and the hacking portion the wire is held.

2. A Wiring terminal construction compris ing a swivel screw held against endn'ise move.- ment, a member having a pair of spaced bearing portions in which said screw is siviveled and an intermediate inclined backing portion, and a nut between said bearing portions engaged and moved axially by said screw, between. which nut and the backing portion the Wire is held, said screw having a head for engagement by a screw drive: and an enlarged portion engaging one oi said bearing portions to hold the screw aga-inst endwise movement.

In Witness whereof, l have hereunto suhscribed my name.

PAUL D. PHLLIPS.
